Hello,
I am getting below error when I try to open the attached contents using Aspose.Cells(V4.4.3.19). I need to convert these contents in to 2007 format.
Contents :
excel tab 1.xls
excel tab 2.xls
FSIDMT_SS_Hypo Table_Pro.xls
Error :
Could not open the input Excel file.
Object reference not set to an instance of an object.
what could be the reason for this error?
Thanks,
Manju.
